How can I start Eclipse Neon/Oxygen under Ubuntu 17.10?

Question

I use Ubuntu 17.10 with

java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)

Since I upgraded from 17.04 to 17.04 I am not able to start eclipse. It always throw the exception:

I tried it with existing and fresh Eclipse Neon and Eclipse Oxygen. Also I tried the tip

--launcher.GTK_version
2

in eclipse.ini and

export SWT_GTK3=0

in the console before starting

./eclipse

I have no clue what I can do to solve this.

On older Ubuntu-Versions the trick with GTK3=0 worked well, but not now. Have you any idea?

Answer 1

I correct myself. I tried already with Oxygen.1a under Ubuntu 17.10.

I found a reason, but not not really understood it. The problem "only" occurs when i start eclipse from console as "root". If i not start eclipse with sudo everything works fine and eclipse not crashes.

Since this combination (Ubuntu 17.10, Eclipse Neon/Oxygen) i did not have this problem. Because i use a complex webapplication with a tomcat-webserver which is deployed and started out of eclipse it was easier to do everything in development as root.

So i need to change my behaviour to get everything running.

So this topic is resolved.
